L-MM Auger electron emission from chlorinated organic molecules under proton impact: angular distribution and total cross section measurement

We have measured absolute total cross section for LMM Auger electron emission of Cl in chlorinated methane and benzene chloride in collision with H+ ion. Projectile energy dependence of the total yield as well as the angular distribution has been studied. Incident proton energy has been varied from 125 keV to 275 keV in steps of 50 keV. C KLL Auger yield have been compared with previous studies and found to be in agreement within the effect of chemical species It has been found that the LMM Auger yield of Cl is much more significantly affected by molecular environment than the C KLL.
